Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics Incidentally, the existing external memory device with wireless communication function was originally considered to be installed in a room, and its operating power was obtained from a commercial power supply through an AC adapter . I have indeed taken various measures to save power during the standby time, but so far, I have not taken any significant effective measures when accessing data. Furthermore, there is no urgent need to do so. On the other hand, for example, the recording medium loaded into a digital camera has been made to have a larger capacity, and in this case, it is unavoidable that the paper sizes must comply with the Chinese National Standard (CNS) A4 specification (210X297 mm). ) -4-583535 A7 B7 V.
